California SWAT+ model packages

Sample SWAT+ watershed model for San Pablo Bay (HUC8 18050002) in California — structure counts, hydrography, national datasets, and Explorer-aligned maps where available.

SWAT+ and SWAT watershed models in California support hydrologic screening, nutrient and sediment studies, and long-term land-management scenarios. This page documents one sample example model from the SWATGenX catalog for California—the largest successful showcase basin on disk for that state—so you can see how the same CONUS data stack and assembly workflow apply in your region. Metrics, maps, and tables are static exports from that completed build (not a live fetch) and are for screening and transparency, not regulatory sign-off.
